TECHNICAL FEATURES
v With high power, small volume and light weight, it is especially suitable for offshore drilling or drilling vessel.
v Under the same liner size, it could run with stroke much higher than the rated value, therefore, it has a wide flow adjustment scope and greatly reduces the times of liner (piston) replacement.
v Split cylinder roller bearing is adopted for connecting rod bottom-end bearing, it allows to replace the connecting rod bearing, crosshead guide plate, etc. without disassembling the crankshaft.
v The crosshead and intermediate rod are connected by spherical hinge head, avoiding eccentric wear of liner and piston essentially.
v The new “J” shaped fluid end with small volume, light weight, sound suction performance and convenience for replacing valve assembly.
v Reduction gears are installed externally with motor on the top to improve transmission efficiency and accuracy as well as save space.
